Wires A, B, C, D, and E meet at a junction point O. The current in wire \(\mathrm{D}\) and \(\mathrm{E}\) is twice as in wire \(\mathrm{A}\) and four times as in \(\mathrm{C}\), respectively. The current in wire \(\mathrm{A}\) is \(4.2 \mathrm{~mA}\) into the junction, and the current in wire \(\mathrm{C}\) is \(5.6 \mathrm{~mA}\) out of the junction. What is the current in wire \(\mathrm{B}\), and in what direction-into or out of the junction-is the current?
